Have a Canon MP270 rinter and when print or make copies it leaves smudges of black ink on the edges. Is there any way I can clean or prevent this without taking it to a pC shop for service?? I do not use it regularly or often but when I do I have to let paper print sit to dry the ink residue. It is mostly on the edges and not the printed part. I do not regularly clean or maintain it but did take it to be cleaned once. Just never knew what to do to maintain it.
